Off-shell diagrammatics for quantum gravity

چکیده
This article reports on how diagrammatic identities of Yang--Mills theory translate to diagrammatics for pure gravity. For this, we consider the Einstein--Hilbert action and follow approach Capper, Leibbrandt, Medrano expand inverse metric density around Minkowski metric. By analogy theory, cancellation are constructed graviton as well ghost vertices up valency six.

Off – Shell Hodge Dualities in Linearised Gravity
In a spacetime of dimension n , the dual graviton is characterised by a Young diagram with two columns, the first of length n−3 and the second of length one. In this paper we perform the off-shell dualisation relating the dual graviton to the double-dual graviton, displaying the precise off-shell field content and gauge invariances. We then show that one can further perform infinitely many off-...
متن کاملAxiomatic, Parameterized, Off-Shell Quantum Field Theory
Axiomatic QFT attempts to provide a rigorous mathematical foundation for QFT, and it is the basis for proving some important general results, such as the well-known spin-statistics theorem. Free-field QFT meets the axioms of axiomatic QFT, showing they are consistent. Nevertheless, even after more than 50 years, there is still no known non-trivial theory of quantum fields with interactions in f...
متن کاملInteracting Quantum Observables: Categorical Algebra and Diagrammatics
Within an intuitive diagrammatic calculus and corresponding highlevel category-theoretic algebraic description we axiomatise complementary observables for quantum systems described in finite dimensional Hilbert spaces, and study their interaction. We also axiomatise the phase shifts relative to an observable. The resulting graphical language is expressive enough to denote any quantum physical s...
متن کاملUnexpected Spin-Off from Quantum Gravity
We propose a novel way of investigating the universal properties of spin systems by coupling them to an ensemble of causal dynamically triangulated lattices, instead of studying them on a fixed regular or random lattice. Somewhat surprisingly, graph-counting methods to extract highor low-temperature series expansions can be adapted to this case. For the two-dimensional Ising model, we present e...
متن کاملNonequilibrium Dynamics and Off-Shell Transport of Relativistic Quantum Fields
S. Juchem, W. Cassing, C. Greiner University of Giessen, 2 University of Frankfurt The dynamics of quantum many-body systems are a challenging task for far-from-equilibrium conditions as appearing in high energy heavy-ion collisions or cosmological problems. It is of fundamental importance to describe abinitio thermalization by taking into account all quantum aspects of the particles (or fields...
